Some people experience heightened anxiety at night, along with a lot of the other symptoms several people have beought up. I often have anxiety attacks in my sleep and they wake me up in some pretty awful ways. Initially I was on the "I won't take anything" stance, but how long do you have to allow yourself to be tortured before you let yourself know that medicine isn't evil?! When an attack occurs, I take Klonopin, and try to go back to sleep. Sometimes that solves the immediate issue, other times it's temporary. My agreement with myself is that if I don't fall asleep within 15 minutes, I won't just lay there staring at the ceiling. I get up and distract myself until I get sleepy or I read until I am literally falling asleep on the book or my Kindle. I know not everyone enjoys books, but they help me tremendously at times to escape my own mind.
